To all wtom it' may concern: v

Be it known that l, MINARD Vil. CHARL- 'V TON, a. citizen of the United States, and a resident of lvart, in the county of Osceola and State of Michigan, have invented a new and improved lVindow-Screen, of which the following is a full, clear, and exact description.

My invention relates to window screens, and has'reference more particularly to self@ winding screens adapted to automatically obstruct any opening made by moving the window sashes and thereby preventing flies from entering through the openings formed by moving. the sashes.

rin object of the invention is to provide a simple and inexpensive arrangement for screening windows.

A further object is to provide selfwindf ing screens so associated with the sashes that the opening formed by the sashes with the window frame is automatically. closed by the screen.

7With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination land arrangement of parts as herein fully described, illustrated and claimed.

ln the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a vertical section through a window provided with an embodiment of my invention; f.'

Fig. 2 is a fragmentary section on line 2 2, Fig. 8; 'f

Fig. 3 is a section on line 3 3, and

F ig. l is a section on line 4 4, Fig. 3.

Referring to the drawings, 5 and 6 are the upper and lower sashes of the window respectively. The upper rail 7 of the upper sash and the lower rail 8 of the lower sash are recessed through their entire length to accommodatea curtain roller 9, preferably mounted to revolve on roller bearings 10 at each end. @ne of the ball races of the bearing forms part of an end plate 11 which closes the end of the recess in the rail and through which the roller is inserted into therecess. l/Vound on each roller is a screen curtain 12, so that the unwinding of the screen from the roller is resisted by a customary spring 13, which in this case has one end thereof secured td" the plate and the other to the roller.

The free end of each screen is provided with a tubular rod 14 reinforcing said end. Said tubular rod accommodates at each end thereof a spring-actuated plunger'or latch l5 for which the window casing has a seat 1G adjacent the window sill for the screen of the lower sash and at the casing top 17 for the screen of the upper sash. W hen the plungers engage their corresponding seats inthe casing, the ends of the screen are tied to the window casing and, consequently. when a sash is moved any opening formed by the displacement of the sash will be barred by the screen which unwinds during the movement of the sash or winds automatically when the sash is moved to the closed position. I

ln cases where it is not desired to have the screen obstruct the window openings formed by the sashes, the latches 15 may be released from the seats by manipulating the projections 18 provided on each latch, and for which suitable slots are provided in the tubular rod 14 (see Fig. i). lVhen the latches are disengaged from their corresponding seats in the window casing, the curtain roller will bringlthe rod-into the recess of the rail; and to allow the rods to enter the recess theend plates 11 arenotched, as shown at 18, forming a stop for the lend of the ylatches projecting out of the tubular rod 141.

l'llo prevent the entrance of flies through the opening formed by the meeting rails of the sashes, a screen section 19 is preferably secured to the under side of the meeting rail of the upper sash to extendto and engage the bearings for the roller, asoreen curtain onfthe roller, a tubular rod secured to the free end of the eutan, Sprngactuated plungers associated with each end of the 5 tubular rod, and seats in the window frame fo'rthe phmgers whereby the end vof the eurtan is secured to the frame So that the opening formed by the displacement of the sash l lar rod when the phmgers are disengaged' from the seats inthe frame, substantially as and for/the purpose set forth.

MINARD WESLEY CHARLTON.
